Tensorflow on Hikey 970

Hello,
I installed Debian with Pre-built Tensorflow which comes with tensorflow 1.4.0-rc0. Whenever I try to install or update tensorflow to latest version, it gives two errors.
ERROR: Could not find a version that satisfies the requirement tensorflow
ERROR: No matching distribution found for tensorflow
I am trying to run various inference workloads but I am not able to. How can I get latest version of tensorflow on Hikey 970?
Thanks.
